Lately I have been using Fusible Fleece by Pellon instead of traditional batting for my work. It is my "third" layer although it is probably my fourth for I use a stabilizer as well! It is thin and soft yet has a nice firmness to it for the small art patterns I have been making. It is 100% polyester. When using decorative stitches and metallic thread it has been perfect. I am wondering what others feel about this? Here is the manufacturers info. Pellon® 987F Fusible Fleece is a one-sided fusible fleece that adds a layer of softness, body, and stability to home decorating, craft and apparel sewing. No Pinning! No Basting! No Sewing! Can be fused to fabric, cardboard, or wood. It is completely sewing machine safe. Black works especially well with dark fabrics.
